- High in the skies over Kazakhstan, spaceage technology has revealed an ancient mystery on the ground.
- Satellite pictures of a remote and treeless northern steppe has revealed colossal earthworks — geometric figures of squares, crosses, lines and rings the size of several football fields, recognizable only from the air and the oldest estimated at 8,000 years old.
- The largest, near a Neolithic settlement, is a giant square of 101raised mounds, its opposite corners connected by a diagonal cross, covering more terrain than the Great Pyramid of Cheops. Another is a kind of three-limbed swastika, its arms ending in zigzags bent counterclockwise.
- Described last year at a conference in Istanbul as unique and previously unstudied, the earthworks, in the Turgai region of northern Kazakhstan, number at least 260 — mounds, trenches and ramparts — arrayed in five basic shapes.
- Spotted on Google Earth in 2007 by a Kazakh economist and archaeology enthusiast, Dmitriy Dey, the so-called Steppe Geoglyphs remain deeply puzzling and largely unknown.
- Earlier Nasa put space photography of the region on a task list for astronauts in the International Space Station.
El Niño covers Chile’s arid Atacama desert in flowers
- Here’s a softer side to the disruptive weather phenomenon known as El Niño: an enormous blanket of colorful flowers has carpeted Chile’s Atacama desert, the most arid in the world.
- The cyclical warming of the central Pacific may be causing droughts and floods in various parts of the world, but in the vast desert of northern Chile it has also caused a vibrant explosion of thousands of species of flowers with an intensity not seen in decades.
- Yellows, reds, purples and whites have covered the normally stark landscapes of the Atacama, where temperatures top 40 degrees Celsius (104 Fahrenheit) this time of year.
- From violet-and-white Chilean bell flowers, or “countryside sighs” (Nolana paradoxa), to red “lion claws” (Bomarea ovallei), to yellow Rhodophiala rhodolirion, they have filled the normally pale desert valleys with rivers of color.
- “This year has been particularly special, because the amount of rainfall has made this perhaps the most spectacular of the past 40 or 50 years,” said Raúl Céspedes, a desert specialist at the University of Atacama.This year’s impressive bloom in Chile’s Atacama desert has brought a big boost in tourism.
- El Niño, which wreaks havoc on world weather patterns every two to seven years, has hit particularly hard this year, causing unusually heavy rainfall in the world’s driest desert.
- That has caused dormant flower bulbs and rhizomes — underground stems that grow horizontally — to germinate.
- “When you think of the desert, you think of total dryness, but there’s a latent ecosystem here just waiting for certain conditions to arise,” said Céspedes.
- The desert flowers are perhaps nature’s consolation for what has been a devastating year for Atacama. The flowers first bloomed in March, after heavy rains that caught the region by surprise and caused massive floods that killed more than 30 people.
- “This is a very unusual phenomenon. Because of the floods in March there was an exceptional winter bloom, which had never before been recorded … and then there was another bloom in spring,” said Daniel Díaz, director of the National Tourism Service for Atacama region.
- “Two flowerings a year is very unusual in the most arid desert in the world, and that’s something we’ve been able to enjoy this spring, along with people from all over the world. There’s a lot of interest in seeing it,” he told AFP.
- The region has seen a 40 percent increase in tourists since the flowers began blooming.
